1 as sea CONVEYER FOR INGANDESCENT IMATERIALS.

Application filed February 13. 1909.

T 0 all whom it may concern:

Be it known that I, RnINHoLo WAGNER, a subject of the Emperor ofGermany, and resident of Berlin, Germany, have invented certain new anduseful Improvements in Conveyers for Incandescent Materials, of whichthe following is a specification.

My invention relates to troughs or like devices for conveyingincandescent materials, for instance coke. When such a trough isconstructed of sheet metal, the different parts of the trough areexposed to a largely varying expansion and contraction as theincandescent material is put on the conveyor and removed therefrom, andalso when cold water is sprayed on the incandescent material andcollects in the lower portion of the trough; and it is the purpose of mypresent invention so to construct the conveyer that the upper portion ofthe trough may expand and contract independently of the bottom of thetrough, without impairing the efliciency and changing the form of thetrough.

In the accompanying drawings I have illustrated two forms ofconstruction embodying my invention.

Figure 1 being a diagrammatic side elevation showing one form of myinvention; Fig. 2 is a partial side elevation drawn upon an enlargedscale; Fig. 3 is a corresponding plan view with parts in section; Fig. 4is a vertical section on line AB of Fig. 2 and Fig. 5 is a correspondingview of another form of my invention; Fig. 6 is an enlarged plan View,partly in section, of the expansion joint shown in Fig. 3; and Fig. 7 isan enlarged vertical section of the joint shown in Fig. 5.

In Figs. 1 to 4 the trough, which is provided with suitable devices (notshown) for spraying water on the incandescent material, consists of ahorizontal portion 6 extending transversely in front of the retorts aand an inclined or rising port-ion c. The incandescent material is fedby any suitable device such as the conveyer chain 19, indicated bydotted lines in Fig. 1. The rising portion 0 is firmly anchored orfastened but the main portion Z) of the conveyor is so supported as tobe capable of movement in the direction of its length. For this purposethe body portion Z) may be supported on balls or rollers, or, as shownin Figs. 1, 2 and 4 on rocking bearings d, which engage the bottom 6 ofthe trough on both sides and are connected Specification ofLetters'Patent.

in pairs by rods f. The bottom a is rigidly connected with the lowerportions 9 of the side walls, for instance by means of angle irons 17L.U-shaped cross pieces 2' are located at'intervals to strengthen saidbottom. The upper portions of the'side walls are generally exposed to agreater heat from the in candescent material than the bottom, which iscooled by the water, and for this reason I have adopted a specialconstruction for the upper part of the side walls, these upper portionsconsisting of individual plates is, which are separated by intervals asshown at m in Figs. 2 and 3 and are connected by bridging plates or fishplates 01, (shown in enlarged view in Fig. 6) so that a considerableexpansion and contraction of the plates is is allowed.

In the construction illustrated by Fig. 5 the upper portions in of theside walls are not connected rigidly with the lower portions but theside walls are divided not only vertically as in Fig. 2, but alsohorizontally or lengthwise. The upper portions 70 have lower edges 0fitting loosely into grooves of the lower trough body and are suitablyheld in this position, as shown in Fig. 7. In this construction theupper portions 70 of the side walls may move independently of the lowerportion of the trough which portion is supported by the tilting bearings(Z and embraces the bottom 6 and the lower side wall portions I thussecure a further protection against the troughs changing its form underthe influence of unequal temperature variations. The lower side wallportions 9 or g should preferably extend to about the highest levelwhich the water assumes in the trough in the ordinary operatlon.

I claim as my invention:

1. A trough for receiving and conveying hot material such asincandescent coke, having side walls of upper and lower portions, theupper side wall portions being provided with vertical slots to allow forthe expansion and contraction thereof independently of the lower sidewall portions.

2. A trough for receiving and conveying hot material such asincandescent coke, the lower portion of which is supported to permitlongitudinal movement thereof and the upper side wall portions of whichare provided with vertical slots to allow for the expansion andcontraction of said portions independently of the lower portion.

3. A trough for receiving and conveying hot material such asincandescent coke, the side walls of which are divided lengthwise andhave their upper parts provided with vertical slots to allow forlengthwise movement of the upper side wall portions independently of thelower side wall portions.

4. A trough for receiving and conveying hot material such asincandescent coke the lower portion of which rests on supports allowingfor a longitudinal movement and the side walls of which are dividedlengthwise and have their upper parts provided with vertical slots toallow for a lengthwise movement of the upper side wall portionsindependently of the lower side wall portions.

5. A trough for receiving and conveying hot material such asincandescent coke having a lower portion provided with grooves at itsedges and having side plates slidably mounted in said grooves.

6. A trough for receiving and conveying hot material such asincandescent coke having a lower portion provided with grooves at itsedges and having side plates spaced apart from one another slidablymounted in said grooves.

7. A trough for receiving and conveying hot material such asincandescent coke having a lower portion and side portions, such sideportions each comprising a plurality of elements, such elements beingmovably connected with each other.

8. A trough for receiving and conveying hot material such asincandescent coke having a lower portion and side portions, such sideportions each comprising a plurality of elements, such elements beingmovably connected with each other and with the lower portion.

In witness whereof I have hereunto set my hand and seal in the presenceof two subscribing witnesses.
